This guide provides clear, step-by-step instructions. We will cover everything from gathering the correct tools to resealing the case back properly.
Following the correct procedure is crucial for maintaining your watch’s integrity and function.
How To Change A Battery On A Bulova Watch
Replacing the battery in your Bulova watch involves more than just swapping a cell. The process requires precision to avoid damaging the delicate movement or compromising the seal that keeps moisture out. This section outlines the complete methodology, from preparation to final testing.
Rushing the job is the most common cause of problems. Patience and a clean, organized workspace are your best tools.
Essential Tools And Materials You Will Need
Before you begin, collect all necessary items. Having everything at hand prevents you from leaving the watch exposed or handling it more than needed. Here is the list of tools you should assemble:
- A set of precision screwdrivers (both flat-head and Phillips).
- Watch case opening tools (a case wrench or a high-quality multi-tool knife).
- A set of plastic or nylon prying tools to avoid scratching the case.
- A pair of fine-tipped non-magnetic tweezers.
- A magnifying glass or loupe for better visibility.
- A soft, clean cloth and a tray to work over.
- The correct replacement battery. This is critical.
- Optional but recommended: a case back holder and a dust blower.
Identifying the Correct Bulova Watch Battery
Using the wrong battery can damage the watch’s circuitry. The battery type is usually printed on the old battery itself, a code like SR626SW or 364. If you cannot see it, you have two reliable options.
First, check your watch’s user manual; it often lists the battery specification. Second, use Bulova’s official website or contact a authorized dealer with your watch’s model number. The model number is engraved on the case back.
Common Bulova battery types include 371, 395, and SR920SW, but never guess. Always verify.
Step-by-Step Battery Replacement Process
Now, with your tools ready and the correct battery identified, you can proceed. Follow these steps in order without skipping any.
Step 1: Prepare Your Workspace
Clear a flat, well-lit table. Place the soft cloth down to prevent scratches and to catch any small screws. Ensure the area is clean and free of dust, moisture, and magnetic fields. Keep pets and children away from your workspace.
Organize your tools on one side. Have your new battery ready, but leave it in its packaging until the moment you need it to avoid static or grease contamination.
Step 2: Open the Watch Case Back
First, determine your case back type. Most Bulova watches have a screw-down case back (with notches) or a snap-off case back (a smooth, seamless fit).
For a screw-down back: Use a case wrench that fits the notches securely. Apply steady, even pressure to turn it counter-clockwise. If it’s stubborn, a case back holder can stabilize the watch. Do not force it.
For a snap-off back: Insert a thin, plastic pry tool into the slight seam between the case and back. Gently twist to pop it open. Work your way around the case, prying a little at a time. Never use a metal knife as it will gouge the metal.
Step 3: Remove the Old Battery
Once the case back is off, place it carefully aside. You will now see the watch movement. Locate the battery; it is usually held in place by a small metal clamp or sits in a plastic compartment.
If there’s a clamp, use a screwdriver to loosen the tiny screw. Do not remove the screw completely; just loosen it enough to release the clamp. Use your plastic tool or tweezers to gently lift the battery out. Note the orientation—the positive side (+) is typically facing up.
Take this oportunity to examine the battery compartment for any corrosion (a white or green powder). If you see any, it needs to be carefully cleaned with a cotton swab dipped in isopropyl alcohol before proceeding.
Step 4: Insert the New Battery
Handle the new battery only by its edges with your tweezers. Skin oils can reduce its lifespan. Confirm the battery type one last time against the old one.
Place the new battery into the compartment in the exact same orientation as the old one. The positive side should match. If the battery does not drop in easily, do not press it; check the alignment.
Once it’s seated, secure the metal clamp back over it and tighten the screw just until it is snug. Over-tightening can strip the tiny threads.
Step 5: Reassemble and Reseal the Watch
This step is vital for maintaining water resistance. First, inspect the rubber gasket—the small O-ring seal around the edge of the case or case back. Check for any cracks, dirt, or deformities.
If it looks worn, it should be replaced. A new gasket is inexpensive and essential. Clean a good gasket with a lint-free cloth and a tiny bit of pure silicone grease to keep it pliable.
Align the case back properly. For a screw-down back, place it on and turn it clockwise by hand first to avoid cross-threading. Then use the case wrench to tighten it firmly, but, again, avoid excessive force. For a snap-off back, align it and press evenly around the edges with a plastic tool until you hear a soft click.
Testing And Aftercare
Once the watch is reassembled, set the time and date if necessary. Gently shake the watch or give it a slight tap to help the second hand start if it’s a quartz model.
Check that all functions (chronograph, date change, etc.) are working correctly. Wipe the entire watch with a clean, dry cloth to remove any fingerprints.
If your watch is water-resistant, have it pressure tested by a professional at your next oportunity to ensure the seal is intact. This is especially important if you plan to wear it near water.
Common Mistakes To Avoid
Being aware of these pitfalls will help you succeed on your first try.
- Using metal tools to pry open a snap-back, which always leaves permanent scratches.
- Forgetting to check and condition the rubber gasket, compromising water resistance.
- Touching the battery or the movement with your fingers, leaving oils behind.
- Over-tightening screws or the case back, which can strip threads or crack crystals.
- Assuming all watch batteries are the same and installing an incorrect voltage or size.
- Not working in a clean area, allowing dust to enter the movement.
When to Seek Professional Help
While DIY battery replacement is achievable, some situations warrant a visit to a watchmaker. If your watch is a high-complication model, a vintage piece, or a prized heirloom, the risk of damage is higher.
If you encounter a case back you cannot open, or if you see significant corrosion inside, professional service is the safest choice. A certified Bulova technician has the expertise and equipment to handle complex issues and perform a full pressure test.
The cost of professional service is often worth the peace of mind, especially for expensive or sentimentally valuable timepieces.
